GB Locale crashes apps like PC-Task?

Just thought I'd report my findings....

I've been trying to run PC-Task - just for the heck of it, really.. Every time
I'd run it it'd do nothing and then the machine would lock solid whenever I did anything else like launching a new shell.

I eventually tracked it down to the locale prefs! If I change my locale to English rather than British English, it works fine!
Change it back to British English and kerblammo! one locked system.

This is probably something nasty in PC-Task but it's something you should all watch out for. Whatever happens it shouldn't take down the entire system....

I've been getting system lock ups. I'll give this a try.
