Valgrind report uninitialized variable somewhere for DInsightMainWindow::getInfoViewLabel()

[petterreinholdtsen]

When running insight under valgrind, I get these messages:

==8413== Conditional jump or move depends on uninitialised value(s)
==8413==    at 0x14240A90: ???
==8413==    by 0x116EC8E7: ???

By running with valgrind --vgdb=full --vgdb-error=1 --error-limit=no insight and attaching with gdb, I get this full backtrace:

I gave it a go, but was unable to make heads and tail to try to track down exactly which structure contain uninitialized memory, so reporting it here in case others have better luck.
