Today I got a new version (2:2.2.1-1ubuntu13.6) of the intel driver and also the intel-dbg package and so I decided to see if this bug still exists. The bug is still easily reproducible unfortunately. However, to my delight the new dbg package seems to provide a much better stacktrace (now I also get some, but not all, DRI function names which I think could be useful):
