My favorite friend in times of crisis like this is 'strace'.
I'm not sure, however, if 'strace' is always functionally equivalent
across all architectures. I'd think that a "mainstream" arch like PPC
would have a fully-functioning strace though. Do 'man strace' and fool
around with it and see if it's doing what it's supposed to be doing.
You'll eventually do something like:
bash$ strace -f -o konq.trace konqueror
That's off the top of my head, so I might have the flags wrong.
Then you look at the trace generated and try to find out where it's
falling over. In about 90% of the time I'm having mysterious "I type
the command and the disk churns for a bit and then I get a prompt again
with no helpful error messages or worse yet, no error messages at all"
strace will show me where the app is failing and I can determine from
there what I need to do to fix it.
strace is one of my favorite things about a Linux system and the lack of
same is one of the things I hate most about having to use a Windows box,
particularly when applications mysteriously fail, which we know *never*
happens under Windows....
