I hadn't considered that, however it's not very enlightening:

Debugger entered--Lisp error: (file-notify-error "Error while trying to read 
file system events")

That error is coming from the inotify_callback function. From gdb the
c-backtrace is:

#0  inotify_callback (fd=16, _=<optimized out>) at inotify.c:139

xbacktrace gives no output at all.

printf time?
