[bug #3395] Segmentation fault in ProjectCenter when run a tool couple times.

[Nikolaus Waxweiler]

Follow-up Comment #5, bug #3395 (project gnustep):

Happens here, too, except that the offending button is named "Build".
1. Open any project or create a new one.
2. Build.
3. GOTO 2 until it throws a NSFileHandleOperationException ("'read' already
in progress" or something) at you or just silently crashes. This is logged to
the terminal: "recursion encountered handling uncaught exception"

Well, as for the backtrace.. the bug doesn't surface when using debugapp and
doesn't leave any coredump behind, either. Arrr. There's some strange things,
though: with each build, two "logErrOut"s are logged to the terminal.
Sometimes, loads of them are outputted at once and the output in the build
output field ("Project Build" window, that gray field) is padded with lots of
spaces. I think that's the point where it usually crashes.
Attaching GDB to a running instance doesn't catch any signals and  when not
using a debugger, "logErrOut"s don't appear during every build...

BTW, pressing "Abort" in these "Critical Error" dialogs even crashes
WindowMaker sometimes. Weee~
