            Bug ID: 3496
           Summary: Crash on double notification popup
    Classification: Unclassified
           Product: Claws Mail (Windows)
           Version: 3.12.0
          Hardware: PC
                OS: Windows 7
            Status: NEW
          Severity: normal
          Priority: P3
         Component: default
          Assignee: users at lists.claws-mail.org
          Reporter: richard.clawsmail at rhughes.net

To reproduce:
1) Install
2) Add an RSS feed with RSSyl
3) Click on newly-added folder: crash

That was the first way I found to cause multiple popups to be created
concurrently. There may be others and hence this may be a duplicate of either
bug 3090 or bug 3130 (or both).

The problem may also occur on non-Windows platforms, but does require a build
without HAVE_LIBNOTIFY. The workaround is to disable
Plugins/Notification/Popup.

Fix:
