Bug #: 33119
           Summary: Free Download Manager freezes randomly
           Product: Wine
           Version: 1.5.25
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Tons of "err:treeview:TREEVIEW_HandleTimer got unknown timer" in terminal after
freeze. GUI of FDM partially works when freeze occurs.
To reproduce the bug:
1. Run FDM
2. Check "View / Groups of downloads" if unchecked (probably it triggers the
bug)
3. Download files until FDM will freeze
