 The frontend from SVN 14490 crashes for me at startup. GDB trace shows
 that a ton of ComboBoxSetting::addSelection calls happen causing the
 segfault. Gdb shows this is in settings.cpp line 1143, backtrace shows:

 (gdb) backtrace

 seen type>, d = 0x819b310, static shared_null = 0x819b310}, d = 0x82a90c8,

 Here is some text from gdb.txt (clipped because it goes on forever until I
 kill the program):
