Sentry Crash Report:

Description stevemcqueen 2015-04-29 22:01:41 UTC 
Using the filesystem browser plugin, when I attempt to manually type in a hidden folder path for my home directory with ~ autocompletion, Kate crashes immediately upon typing the '.' (period) character.

examples of what crashes and what doesn't:
/home/user/Documents -> works
/home/user/.kde -> works
~/Documents ->works
/.test/ -> works
~/.kde -> crashes
~/.test -> crashes


Reproducible: Always

Steps to Reproduce:
1. open kate, with file system browser plugin loaded
2. click on the filesystem browser's path, clear it
3. begin typing a hidden folder in the home directory with tilde (~/.kde/)

Actual Results:  
Kate completely crashes once you type the period '.' character.

I ran Kate off the command line and got this output when trying to reproduce:

doesn't know ""
kf5.kio.core: KLocalSocket(0x1bd4580) Jumbo packet of 71878 bytes
kate: ../../../src/widgets/kurlcompletion.cpp:280: virtual void UserListThread::run(): Assertion `m_prepend.isEmpty()' failed.
Aborted (core dumped)


Expected Results:  
Application should continue working and allow me to type and enter the ~/.kde folder.

I'm running Kubuntu 15.04, KDE Frameworks 5.9, Kate 5.0.0

Crash didn't offer any other useful information besides the message above.
Comment 1 Milian Wolff 2015-06-06 20:43:30 UTC 
I can also reproduce this 100% of the time. Just need to press "CTRL + O" in kate, and then type in e.g. "~/." and it will crash with the assert above:

Application: Kate (kate), signal: Aborted
