not reproducable on Debian unstable. Do you have a backtrace?

like SDA4PP?
I removed SDA4pp and disabled all the other and I still have the crash with the same message
Warning: QPixmap: It is not safe to use pixmaps outside the GUI thread Warning: QPixmap: It is not safe to use pixmaps outside the GUI thread Segmentation fault
I'm using the ubuntugis repositories and qgis trunk compiled from source.

Confirmed QGIS crash on Slackware linux. Under Windows XP merging the following files works fine. But on Linux QGIS craches too when I try to open shapefile pen_01.shp. Here is debug output before crash

I guessed that was a problem in one of the shapefiles, nevertheless it should not crash.
PS I'm using GDAL 1.7

Looks like it crashes within OGR. OGR_L_GetNextFeature doesn't return...
