I can reproduce a similar crash with shares in a linux machine with long
names like
smb://127.0.0.1/Partage Mint-land mas largo aun pero sin caracteres raros/
smb://127.0.0.1/workgroup.Partage.Mint-land_mas_largo_aun123
4pero_sin0_caracteres_raros/
What I do:
in Kate "Save copy as", click on network -> "Recursos compartidos de
Samba", it can't find any workgroup (I'm not good configuring samba :-().
modify the url to smb://127.0.0.1/ and Enter
Click on one of the folders, and then on Save, it is saved.
Again, "Save copy as", click on network -> "Recursos compartidos de Samba",
and Crash.

I'm working in KCoreDirListerCache right now.
https://phabricator.kde.org/D10742
But it doesn't solve this crash, I'll try to fix the crashes.
