Description
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 #0 ComboBoxSetting::addSelection (this=0x82a9028, label=@0xbfed2540, value={static null = {static null = <same as static member of an already seen type>, d = 0x819b310, static shared_null = 0x819b310}, d = 0x82a90c8, static shared_null = 0x819b310}, select=false) at settings.cpp:1148 #1 0x080d373e in AspectOverride?

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