I've copied this over from the D Learn list because I haven't had a response so far.
I'm assuming the problem is with my code. Anyway the full source is here:
https://github.com/mark-summerfield/debfind
And here's the problem:
When I ran the program I did Find 'memoize' which worked. Then 'memoize python' which also worked. Then said to find 'any word' (which produces 1000s of rows) at which point it crashed. Below is the bt. Does it look like my bug or a Gtk or GtkD bug?

(DebFind:2436): Gdk-ERROR **: 15:48:40.080: The program 'DebFind' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial 12790 error_code 11 request_code 130 (MIT-SHM) minor_code 5)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Thread 1 "DebFind" received signal SIGTRAP, Trace/breakpoint trap.
