Electrum: malformed launcher command

[fliteshare]

Linux Mint 18.3 (sylvia)
kernel x86_64 Linux 4.15.0-15-generic
electrum 3.1.3

icon launcher properties
Installed Command: [sh -c "PATH=\"\$HOME/.local/bin:\$PATH\" electrum %u"]
throws error: "unknown command %u"
Please change Command to: [sh -c "PATH=\"\$HOME/.local/bin:\$PATH\" electrum"]
to make it work !

Thank you.

@fliteshare the most important information is missing here: what is the launcher that cannot cope with the %u? I have no issues on Gnome3. Also, the launcher file passes validation:

desktop-file-validate electrum.desktop
electrum.desktop: hint: value item "Finance" in key "Categories" in group "Desktop Entry" can be extended with another category among the following categories: Office

Furthermore, launching electrum from the commandline works too.

gtk-launch electrum.desktop

It doesn't work in kde either. Adding a semi-colon after the path variable fixes it for me:

Exec=sh -c "PATH=\"\\$HOME/.local/bin:\\$PATH\"; electrum %u"

One problem is that for KDE users the launcher fails. To reproduce try:

# kioclient5 exec electrum.desktop 
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 7: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 7: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 21: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 21: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 7: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 7: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 21: " "Invalid escape sequence \"\\\"\"."
"KConfigIni: In file /home/david/Projects/electrum/electrum.desktop, line 21: " "Invalid escape sequence \"\\\"\"."

IMHO, just set Exec=electrum %u and let the OS maintainer set the path appropriately.

@dmp1ce what about fixing the KDE laucher?

[dmp1ce]

@toxeus Well, I'm not sure where to report the issue or where the source is. I asked for help here: https://forum.kde.org/viewtopic.php?f=304&t=154126

@dmp1ce https://bugs.kde.org/

[dmp1ce]

@toxeus Thanks. I knew about KDE's bugzilla but I didn't know which project to file the bug under and I also couldn't find any previous bugs related to escape sequences which surprised me.

Just wanted to mention what @AbdussamadA wrote above works on the older KDE4 too (adding a semicolon).

KDE4 is end of life (but still has many users I think) so bug reporting is probably not of much help in my case.

Ok.. so with a semicolon there, at least it launches, even if it fails to modify PATH? Anyone against adding a semicolon then?

[dmp1ce]

Well, kioclient5 exec works with the semicolon but launching through the GUI doesn't work for me. I'm not sure why the results are different.

[SomberNight]

There was another user running into this and getting "stuck" on it today...

I'm testing this now on Manjaro-KDE (17.1.12) which has kioclient 5.13.5.
The original command is

sh -c "PATH=\"\\$HOME/.local/bin:\\$PATH\" electrum %u"

but for some reason the launcher actually executes

sh -c "PATH=\\$HOME/.local/bin:\$PATH\ electrum %u"

The semicolon trick works here; let's do that until someone has a better solution.
