Bug#846551: qtractor: Hangs when opening a file chooser dialog

[Philip Chung]

Package: qtractor
Version: 0.8.0-1
Severity: important

Dear Maintainer,

Whenever I perform an action that opens a file chooser dialog, Qtractor
simply hangs. There is no error in the Messages area, and running it
through GDB does not indicate any crash.

The actions I have tested are opening a project (either from the
toolbar, the File menu, or the keyboard shortcut) and choosing a
location to save a project.

I have also tried loading a sample in a drumkv1 LV2 plugin, which also
requires a file chooser. It causes Qtractor to hang as well. This does
not occur with the standalone version of drumkv1. I am using source
version 0.8.0-1 of drumkv1.
