Comment 11 for bug 1074260

Additional information:
With SeaMonkey 2.13.1 when an attachment cannot be opened (doubleclick on attachment, the saved temporary file is not correct and the started application throws an error), a repair fixes the problem for 1 try, the problem comes back when re-visiting the same message and another repair is required.
With SeaMonkey 2.13.2 and a freshly created .msf it works OK, but when repair is selected the problem then occurs. (inverse of 2.13.1)

This is a setup where IMAP is used (UW IMAPD) and folders are NOT synchronized for offline use.
So the file growth is not visible, but there still are problems.
