Description Bill Wayson 2017-10-18 03:22:16 UTC 
Application: kstars (2.7.10)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.5-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:  I had simply clicked the 'X' button in the upper right of the kstars window.  Kstars closed, and a message that it ah closed unexpectedly appeared immediately.  I tried this twice with the same results.

The crash can be reproduced every time.

-- Backtrace:
Application: KStars (kstars), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Can you try with version 2.8.6?
Comment 2 Bill Wayson 2017-10-21 22:50:02 UTC 
Hi Jasem,

I'd like to, but I am having trouble finding an installation source.  And the rpm version numbers I see don't seem to correspond to the kstars version (e.g. my kstars 2.7.1 comes from the kstars-17.08.1-1.1.x86_64 rpm file).  From the various openSUSE repositories I see, 17.08.1 seems to be the latest rpm available.  I see you have an Ubuntu/Mint repository.  Do you have any suggestions?  Will I need to build from source?
Comment 3 Jasem Mutlaq 2017-10-22 05:33:17 UTC 
Not sure if there are bleeding-edge versions of KDE or KStars on OpenSUSE. So you have to build from source if you can't find any. On Ubuntu, there is a PPA with frequency updates.
Comment 4 Bill Wayson 2017-11-02 20:18:58 UTC 
Hi Jasem,
     First, thank you for all your work on Kstars.  Now, after running kstars for a bit and shutting it down and restarting it several times, it no longer seems to crash upon closing under Tumbleweed.  The kstars version is still 2.7.10, but Qt is now at 5.9.2, Frameworks appears to be at 5.39.0, and the kernel is 4.13.10-1-default x86_64.  Tumbleweed is at version 20171101.
     Let me know if there is anything else you'd like.
Comment 5 Bill Wayson 2018-03-02 15:46:08 UTC 
Hello Jasem,

I want to report that, despite my 2017-11-02, the crashing problem when closing Kstars under openSUSE Tumbleweed did reappear.  But, since then, version 2.9.2 of Kstars was installed from the Tumbleweed update repository, and the crashing problem has disappeared.  It has not occurred to me since the update, which was a while ago.
