Bug#598817: [traverso] Crashes when opening file dialogs in KDE4

[Daniele Benucci]

Package: traverso
Version: 0.49.2-1
Severity: important

--- Please enter the report below this line. ---

Traverso crashes when first starting in KDE4 environment with the following 
output in console (crash is catched and a dialog box is shown, then program is 
terminated):

---console output---

---end of console output---

If manually editing ~/.traverso/Traverso-DAW/Traverso.ini as stated in 
http://savannah.nongnu.org/bugs/?30401#comment0, traverso starts and works, 
but crashes in the same way every time a file dialog should be opened (eg.: 
Edit->Import audio or Project->Open Project->Select Project Dir.

Still crashes starting with a clean user profile or without DE (xterm-only X 
session).

Does not crash in a sid virtual machine running e17.

Does not crash in xterm-only session if running with Qt's GTK+ theme/engine 
(using Raleigh GTK theme) or changing theme to Qt's GTK+ one while running 
(when this theme is selected GTK file dialog is shown). After this change all 
other Qt themes do NOT trigger the crash until program is closed.
Unfortunately trying the same steps when running Traverso in a KDE4 session 
does not help (may be related to KDE font and color settings applied to GTK 
applications).
