Description Edward 2020-09-26 22:55:07 UTC 
Description of problem:
When using the MATE, LXDE, LXQt or XFCE desktop environments, if changing the desktop theme 
or window border in any of those deskops while Claws Mail is also running, Claws immediately crashes. 
Was able to duplicate this crash many times.

Version-Release number of selected component:
claws-mail-3.17.6-1.fc32

Comment 12 Edward 2020-09-27 18:20:41 UTC 
Both LXDE and LXQt technically have two methods to change the theme or
window border. One way is to go to Preferences/Customize Look and Feel/Window Border (CLF). 
The other is to go to Preferences/Openbox Configuration Manager/Theme (OCM). 

For both desktops, the OCM method is the proper way to change the
theme/window border, which I did not know beforehand. All this time, I
had been using the CLF method - which actually performs the same
procedure.

I disabled GLX to see if perhaps it was related to these crashes. 

On this system (with an AMD Radeon 3000 GPU), the following occurred:

With GLX disabled:

LXDE - Using the CLF method, no crash.
       Using the OCM method, no crash.

LXQt - Using the CLF method, crash.
       Using the OCM method, no crash.


With GLX enabled (the system default for a new installation):

LXDE - Using the CLF method, crash.
       Using the OCM method, no crash.

LXQt - Using the CLF method, crash.
       Using the OCM method, no crash.

With and without GLX enabled, Claws continues to crash with the MATE and
XFCE desktops when changing the themes via the proper method for both
those desktops.
Comment 13 Michael Schwendt 2020-09-27 23:06:40 UTC 
You have reported this to upstream already. It is not specific to the packaging done by Fedora.
Comment 14 Edward 2020-09-28 12:48:35 UTC 
libgobject is causing Claws Mail to crash/seg fault.
Comment 15 Edward 2020-10-08 12:16:44 UTC 
A new glib2 package was released. With this new version installed, I was unable to get Claws Mail to crash from the information in Comment 12 using the LXDE desktop.
