Centaurus 3.6 TDE R2 - GTK apps broken by config tools

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 Centre utility for configuring GTK applications to check how a GTK theme would behave.
That theme was not installed at this time.

I installed:-

robin@flopsy:~$
Start-Date: 2019-04-28  06:54:05
Commandline: /usr/sbin/synaptic
Requested-By: robin (1000)
Install: gtk-qt-engine-trinity:amd64 (4:14.0.6-0debian10.0.0+0~a), kgtk-qt3-trin
ity:amd64 (4:14.0.6-0debian10.0.0+0~a), gtk3-tqt-engine-trinity:amd64 (4:14.0.6-
0debian10.0.0+0~a, automatic)
End-Date: 2019-04-28  06:54:08

Following reboot neither Firefox nor Thunderbird would run

(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

robin@flopsy:~$ firefox

(firefox-esr:1025): Gtk-ERROR **: 09:46:15.111: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported

robin@flopsy:~$
(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

Removing the installed packages resolved the problem. I have not installed this utility on any version of Centaurus before so I do not know if this is a new bug or a recent arrival.

We can confirm the issue, it's reproducible on Q4OS Scorpion as well as Centaurus, we are going to investigate that. A feedback will be posted here as soon as a new information will be available.

It is reproducible on a plain Debian/Trinity stable system as well, so considered as a Trinity bug. The culprit is the "kgtk-qt3-trinity" package, it's the one that causes crashes of some GTK3 applications. We will pass that at the Trinity bug tracker. Thanks for reporting.
