            Bug ID: 13813
           Summary: SEGV (11) on USB-flash connection
    Classification: Xfce Core
           Product: Thunar
           Version: 1.6.10
          Hardware: PC (x86_64)
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Medium
         Component: General
          Assignee: xfce-bugs at xfce.org
          Reporter: mikhail.kasimov at gmail.com

                CC: benny at xfce.org, hjudt at xfce.org
  Target Milestone: 1.8.0


've got segv (11) on USB-flash connection. I suppose, this situation was, when
Thunar tried to get USB-flash at the same time with VBox VM. Anyway, seems to
be better to show some alert-window instead of segfaulting.
