gmc crashes on weird filenames

[Ronald de Man <deman win tue nl>]

Starting gmc from my home directory results in a crash:

(gdb) file /usr/local/bin/gmc
Reading symbols from /usr/local/bin/gmc...done.
(gdb) run

This generally means that the program could not talk to the esound server

Gmc doesn't crash immediately when started from a different directory.
The moment I select my home directory it dies.

I mentioned a crash like this before, and added it was probably caused
by the large number of files and directories in my home directory.

But looking at the backtrace and my home directory, it appears that
I have a file with a name consisting of a single newline (no idea
how it got there), and this causes gmc to crash.
