Firefox 7 crashes when trying to create subtasks in Jira 4.4.3

Problem report from a customer upgraded to 4.4.3 customer has noticed that they no longer can create a sub-task as Firefox (all versions from 3.6.23 to 7.0.0) crashes when opening the drop box to select the sub-task issue type.

The customer has been holding off in giving a backup but has supplied html which replicates their crash when opening the drop down to select the sub-task issue type.

Hi Michael, this seems to be closely related to the size of the string:

the crash file is the complete label string as copied above in a simple html code, it full crash firefox.
The work2 was the temporary file with a shorter string, it makes firefox hang (not crash as brutally), but unrecoverable either.
the ok file is a very short version of the file and load just fine....
BTW, the list includes project (at the end) starting with 'zzz' which are archived projects. Those projects have a special "Permission Scheme" that doesn't allow anyone to create/update/close issues, so why are they appearing in that list ?

Best Regards,
Johan.

When FF is executed in the command line and sub-task-crash.html is used this error message comes up:
