i cannot click any links in teamspeak (chat, server button, etc.), and the console puts out on every click:

Cannot mix incompatible Qt library (version 0x50402) with this library (version 0x50500)
Aborted (core dumped)
I am pretty sure this problem is caused by a QT library that is missing in the TS download package so it is loaded from system sources which differ in version.
Most likely this is also the reason why this bug was not found, on time of testing the system QT version on the testers machine was most likely the same version as used in Teamspeak.

I ...
- use Kubuntu 15.10
- use TS3 x64
- use the TS start script
- have an up-to-date system and TS

One quick fix could be to download all Qt libs for linux in version 5.5.0, but the downloads on the QT website only has some weird binary installer and i don't want to run that.
