Thunderbird crashes when saving an email as a file with a colon in the filename.

Binary package hint: thunderbird

Thunderbird crashes when I do the following:
- Open an email with attachments.
- File > Save As > File
- Leave the default filename in place (which was "Fw: sunday 25 May.eml")
- Select type "Text files"
- Click Save.
It then gives an error message which says:
   Unable to save the attachment. Please check your filename and try again later.
On clicking OK, thunderbird crashes with "Segmentation fault" to the command line.
