Description Franz Trischberger 2014-05-27 07:29:50 UTC 
Using qupzilla I get te following backtrace:
#0  0x0000000000000040 in ?? ()

It crashes in harfbuzz. Enabling USE=harfbuzz for qtgui made the crash go away (qupzilla runs and get's used since more than a day now).

Still reproducible with 5.3.1?

problem seems to be gone with 5.3.1.
