[workaround] Firefox, Seamonkey, Thunderbird crashes in KDE4 when using File Dialog (File open/File save)

[Zbigniew Luszpinski]

Hello,

because of rapid and hidden removal of qt3 and kde3 many apps may remain broken or fail to start after lunar update.
Here are few fixes you can do to fix this total disaster.

After removal of kde3 and qt3 gtk apps will refuse to work or will work partially in kde4 and qt4.
The typical bug is when you use kde4 and in firefox/seamonkey/thunderbird you try to open/save any file these apps will crash.
How to workaround them:

Firefox - in address field (here where you usually type in http:// address) type in about:config
In filter bar type in: ui.allow_platform_file_picker
If the ui.allow_platform_file_picker is listed change it value from true to false.
If nothing was found right click in the window and from context menu choose:
New->Boolean
preference name: ui.allow_platform_file_picker
value: false

Seamonkey - the same steps like in firefox

Thunderbird - menu "Edit"->"Preferences"->"Advanced" tab->"General" tab->"Config Editor..." button
In filter bar type in: ui.allow_platform_file_picker
If the ui.allow_platform_file_picker is listed change it value from true to false.
If nothing was found right click in the window and from context menu choose:
New->Boolean
preference name: ui.allow_platform_file_picker
value: false

gimp - I have no idea yet how to fix this app.
other gtk apps  - I have no idea yet how to fix them.

If you know any application for my mobile Siemens ME45 (they removed kmobiletools) let me know :(
If you know how to fix other gtk apps crashing under damn KDE4 let me know :(

have a nice day,
