Hey DM,

I went to use uedit today and it segfaults - I couldnt seem to get dbg to get any meaningful backtrace (beyond my skills really). Strange thing though, when I used valgrind, it ran.

The last few lines of an strace is below - in case it is helpful:

2184 poll([{fd=0, events=POLLIN}], 1, 0) = 0 (Timeout)
2184 write(1, "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 190) = 190

Re: UEDIT - segfaults

First thing, try a clean re-build: http://wiki.synchro.net/install:nix#clean_rebuild

Then if it still happens, run it under gdb to capture the backtrace: http://wiki.synchro.net/howto:gdb
