Hi,

gideon crashes when loading a large c++ project (eg. gideon itself). 
I tried to reproduce the bug and got two different behaviours.

1.: Running gideon without gdb lets gideon simply disappear  (without KCrash) when parsing the project files...
console says:  "Der Wecker klingelt." :) poor German translation - it means "SIGALARM received".

2.: Running gideon in gdb does not yield this error. But when my box is under high load it yields another error when parsing the project files:  SIGSEGV.

The backtrace for the SIGSEGV varies:

GNU gdb Red Hat Linux (5.2.1-4)
Program received signal SIGSEGV, Segmentation fault.
