dentry edit, occasional trailing garbage, sigsegv

[John Ellis <johne bellatlantic net>]

I noticed the dentry edit widget used by gmenu and the panel would
(more than) occasionally add trailing garbage characters. When saving
a dentry.

So I linked gmenu with Electric Fence, here is the backtrace:

ho hum, I can't seem to find the exact problem. The offending .desktop file
looks fine:
