Firefox crashes after printing

[Jonathan Ryshpan]

Firefox crashes after printing or print preview.  Print or preview
works OK, then Firefox terminates immediately, closing its window
without any message.  The problem seems to have started with
version 1.5.0.2, which is the first version of Firefox to have
the print plugin libunixprintplugin.so in the plugins directory.
The problem has continued with FC6.

Has anyone else seen this?  If so, does anyone know of a cure?

I'm running Firefox-1.5.0.7 under FC6 with all updates installed.

Thanks - jon
