There should be no crashes related to QRegExp and threading since Qt 4.4. If 
you find something, it's usually because you used the same QRegExp object to 
conduct searches at the same time.

Make sure you operate on a QRegExp object that isn't in use by any other 
thread. Create a copy if you need to.

If the problem persists, it would be nice to have a clean testcase so that the 
bug can be fixed. A helgrind log would help too.
