Segmentation fault on application startup.

[Sadario]

I am running Arch on this laptop, with a mate desktop environment. Below are the relevant outputs from 'journalctl' and 'guake --support', as well as the contents of the session.json-file. I have also tried running 'guake -u', which does not change the behaviour.

Deleting/renaming '~/.config/guake/session.json' solves the problem temporarily. Guake now starts, but after a clean shutdown of the application, it will not start again.

I really hope someone can help me with this issue, as I would love to get back to using this brilliant software.

Seems to be a duplicate of #1739.

@Sadario unchecking the experimental startup and restore tab options seems to fix this problem for me.

[Sadario]

With limited testing, I can also confirm that this seems to fix the issue.

Deleting session.json fixes it. I am able to trigger this bug by killing guake or running it in another terminal and killing it with ctrl C. The result the segfult deleting session.json lets you start the application again

Hey, thanks for nice report; however let me close this as duplicate of #1641 and #1749 (which are both the exact same issue, i.e. dupes, too).
