Hi,
I've been trying to get the blackbox window manager to work properly with
uClibc 0.9.29 with no success. I had it working fine in the past with uClibc
0.9.28, now it segfaults during startup with 0.9.29. I noticed that if I
delete the /usr/share/blackbox/styles directory, blackbox will run ok, but
obviously it doesn't apply the colors and fonts and other niceness. Here is
a stack trace from Eclipse using avr32 gdb:
Thread [1] (Suspended: Signal 'SIGSEGV' received. Description: Segmentation

I'm not sure where to go from here, any debugging tips you folks can offer
would be greatly appreciated.
Thanks,
