[Qgis-developer] 2.2 project keeps crashing after load

[Andreas Neumann]

Hi,

I believe it has to do with layers that have automated labeling on
polygon layers with free or horizontal label placement algorithm.

If I turn off these layers the crashes do not appear. I can then later
turn on the visibility of these layers and it will work fine.

I will try to create a test project with the same labeling settings and
the data in an sqlite db for testing.

When QGIS crashes, I always get the "QPixmap: it is not safe to use
pixmaps outside the GUI thread" message.
