By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Q4OS Team 2019-04-30 15:22:56 CDT

After installation I added T/bird and Firefox - which both ran as expected. Although I do not normally use it anymore I decided to install the Control panel utility for configuring GTK applications to check how a GTK theme would behave. I installed "kgtk-qt3-trinity:amd64" package. Following reboot neither Firefox nor Thunderbird would run:

[code]
(thunderbird:947): Gtk-ERROR **: 09:43:41.324: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
ExceptionHandler::GenerateDump cloned child 969
ExceptionHandler::SendContinueSignalToChild sent continue signal to child
ExceptionHandler::WaitForContinueSignal waiting for continue signal...
Trace/breakpoint trap
robin@flopsy:~$ firefox

(crashreporter:1034): Gtk-ERROR **: 09:46:15.230: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
[/code]

Removing the installed package "kgtk-qt3-trinity:amd64" resolved the problem.

Exact steps to reproduce:
- Fresh TDE stable (14.0.6) installation on Debian Stretch.
- Install "thunderbird" package: sudo apt install thunderbird
- Perform a testing Thunderbird run, it runs fine.
- Install "kgtk-qt3-trinity" package: sudo apt install kgtk-qt3-trinity
- Run Thunderbird once again from terminal
- Bug: Thunderbird doesn't start, prints error messages above

In addition, it's required to reboot after kgtk-qt3-trinity installation, so the more precise steps to reproduce the bug are as follows:
- Fresh TDE stable (14.0.6) installation on Debian Stretch
- Install "thunderbird" package: sudo apt install thunderbird
- Perform a testing Thunderbird run, it runs fine.
- Install "kgtk-qt3-trinity" package: sudo apt install kgtk-qt3-trinity
- Reboot
- Run Thunderbird from terminal again
- Bug: Thunderbird doesn't start, prints error messages above

The kgtk-qt3-trinity package has always been a source of trouble. Although Michele has made efforts to address key issues, the package remains a source of trouble and we always recommend that you avoid installing the package.

Package kgtk-qt3-trinity is not related to GTK+ theme settings. Here are the gtk-qt-engine-trinity and gtk3-tqt-engine-trinity packages.
