Bug ID: 397200
Summary: Crash when kstars window is not in front when starting
Product: kstars
Version: 2.9.7
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: eric.dejouha...@gmail.com
Target Milestone: ---
Issue is difficult to reproduce, and I don't immediately see the relation with
the z-order of the kstars window. But I can reproduce the issue using the
following scenario:
1. Start kstars, let the splash screen appear
2. While splash screen is there, alt-tab to another window
3. When objects are being loaded, kstars crash with the following backtrace:
Thread 9 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.
