           Summary: Crash when saving/opening an attachment
           Product: kmail2
           Version: 4.7
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: alvanx at gmail.com


Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

This started to happen this week. The crash either occurs right when clicking
the attachment, or after I've picked the location to save it. Sometimes no
crash happens; I havn't found a pattern. In one case I was finally able to save
a specific attachment after it had crashed about 4 times before. Most times it
crashes. This happens with different file types, I specifically remember pdfs
and different kinds of documents and presentations. 

Could be a duplicate of https://bugs.kde.org/show_bug.cgi?id=287177. 

Reproducible: Sometimes

Not sure how valuable this backtrace will be, it has a one star rating, but
it's with debug packages.
