[Bug 1971091] Re: kstars 3.5.7 crashes with segfault on startup on 22.04 and 22.10

[Rik Mills]

** Description changed:

  U/Kubuntu 22.04
  Package: kstars
  Version: 5:3.5.7-1
  
  Also see: https://bugs.kde.org/show_bug.cgi?id=453239
+ 
+ [Impact]
+ 
+  * The application segfaults on start, so is useless in its current
+ state
+ 
+ [Test Plan]
+ 
+  * Does it start ok?
+ 
+  * Tester familiar with kstars may wish to test if there are any
+ regressions in functionality compared to previous releases.
+ 
+ [Where problems could occur]
+ 
+  * Regressions in functionality compared with previous releases. Unless
+ major, these may not be a blocker to this fix and a follow up SRU would
+ be more appropriate.
+ 
+ 
+ ********** original bug description below ***********
