Asbru-cm: asbru crash after manual RDP session disconnection

[vibo69]

any RDP session on rdesktop makes crash asbru if I right click on connection tabs and choose disconnect session. reproducible on last stable and also on loki branch

[popxunga]

BTW, this is the error on crash (on EL7) running the latest loki build:

(asbru-cm:5158): Gdk-ERROR **: 18:05:58.409: The program 'asbru-cm' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 828997 error_code 3 request_code 131 (XInputExtension) minor_code 40)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

@vibo69 Would you mind using the bug template ? In particular, what OS are you running with ?

As a matter, I cannot reproduce it on my Ubuntu 18.04 system nor on a plain CentOS 7 VM.

Yes with Debian 10 + xfce, I can reproduce the problem.

@popxunga Are you also using xfce on your EL7 ?

@gfrenoy ... RHEL 7.7 with gnome3 here.

[gfrenoy]

I believe I found out the root issue and was able to find workaround: the RDP window needs to be hidden before disconnecting the connection.

The fix is available on the loki branch, let us know if it fixes the issue for you.

Hi @gfrenoy ...

I'm currently unable to install the latest loki build on EL 7.8 due to dependency issues:

Resolving Dependencies
--> Running transaction check
---> Package asbru-cm.noarch 0:6.3.0~1590344834-1.el7 will be updated

Error: Package: asbru-cm-6.3.0~1591014959-1.el7.noarch (rhel7-xxx-xxx-xxx)
           Requires: perl(Gtk3::TreeView)
 You could try using --skip-broken to work around the problem

I've built perl-Gtk3-SimpleList-0.21 and perl-Gtk3-0.037 from FC33 source but the TreeView pod is not included in those packages. So, at this moment I'm not sure where to get the missing library.
Any ideas ?
Thanks.

[gfrenoy]

Mm? Very surprising !

Gtk3::TreeView is supposed to be provided by perl-Gtk3 so there is no reason to have a specific package for this.

And moreover, we don't have this requirements in our spec file...

I would believe the rpm packaging system is trying to be clever and saw that change:

https://github.com/asbru-cm/asbru-cm/commit/580367fe423ef61526517027be0ccdc49e66a219#diff-a1cfee7728b9037161906e720415bcb1L11

and thought it requires an additional package Gtk3::TreeView.

Let me see how I can convince that beast to leave me the control on the requirements...

Hi @gfrenoy
I was able to successfully Install the loki build after the 2nd attemp of #538.
Tested the disconnect from Tab context menu in one RDP connection and it worked fine, no crash :-)
Thanks for your support.

[gfrenoy]

Wonderful !

Thanks to you for always being the first one to try the "bleeding edge" features, your contribution is very much appreciated :sunglasses:

Let me also know if this eventually fixed this issue/crash :boom:

[popxunga]

Yes ... you probably didn't notice it, but I wrote that I tested the disconnect from the RDP tab context menu and it worked fine. So, the crash issue is fixed as well :-)

[gfrenoy]

Indeed, I read a bit too fast your last message !

So it's a double "Wonderful !" that you get :)
