If you can reproduce the crash, please install debug symbols for the dolphin-plugins package. See https://community.kde.org/Dolphin/FAQ/Crashes

They are installed.....
Comment 3 Tony 2018-04-05 09:32:21 UTC 
....Unless for some reason on Fedora you need the debugsource as well.
Comment 4 Elvis Angelaccio 2018-04-05 19:57:46 UTC 
No idea about Fedora packaging, but

  #16 0x00007f1ff49a4ebc in PushDialog::PushDialog(QWidget*) () from /usr/lib64/qt5/plugins/fileviewgitplugin.so

means that this plugin (which should be part of dolphin-plugins) doesn't have debug symbols available.

New crash information added by DrKonqi

dolphin (18.07.70) using Qt 5.11.0

- What I was doing when the application crashed:

I hit "Git Push" while inside a clone repo from https://github.com/RobertBeckebans/RBDOOM-3-BFG.

The cloned repo was copied from a Fedora 27 system were i experience the same issue, but could not reproduce easily. Here is 100% sure crash if you hit "Git push".

This is on a Opensuse Tumbleweed system.
Comment 7 Christoph Feck 2018-06-15 00:00:45 UTC 
Elvis, is backtrace from comment #5 sufficient to pinpoint the issue?
Comment 8 Elvis Angelaccio 2018-06-16 16:04:30 UTC 
Hmm. Could be that `currentBranchIndex` does not get initialized which would explain why `branches.at(currentBranchIndex)` crashes.

A valgrind log would be very helpful, if the crash is 100% reproducible.

Valgrind log
Comment 10 Elvis Angelaccio 2018-06-16 17:12:52 UTC 
Ok, not what I was thinking of. Could be a bad allocation of memory for the strings containing the branch names.

Can you show the output of "git branch -a" in the repository from which you are triggering the crash?
Comment 11 Tony 2018-06-16 20:41:00 UTC 
I hate myself as i type this, when i typed git branch -a i realized somehow Git was removed from my opensuse system from which i got the valgrind log and the 2nd bracktrace. F me.

git branch -a out "after" i re-installed Git:

  branch_remotes/origin/vkdoom3-merge
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/IBL-environment-probes
  remotes/origin/flash-tools
  remotes/origin/flash-tools-lua

Comment 12 Elvis Angelaccio 2018-06-17 08:13:57 UTC 
Does it still crash after you reinstalled git?
Comment 13 Tony 2018-06-17 16:31:13 UTC 
(In reply to Elvis Angelaccio from comment #12)
> Does it still crash after you reinstalled git?

No, while using git push.
Comment 14 Elvis Angelaccio 2018-06-18 20:20:20 UTC 
What I meant was: can you still reproduce the crash when pressing "Git Push", even if have installed git?

(In reply to Elvis Angelaccio from comment #14)

No, on my opensuse system i haven't seen any crashes with "git push" after installing git.
Comment 16 Elvis Angelaccio 2018-06-19 20:36:45 UTC 
Thanks, I'll close this report for now then.
