I'm getting this same error with the plugin. It seems to happen after disconnection, but not immediately. If I say something that would trigger a push, or attempt to reconnect to znc, then it will trigger the crash.

It persists and crashes with this error on restart until I rm the colloquy .registry file, then things work again until I register a new device and disconnect/reconnect or restart the bnc, and then it happens again.

Using znc 0.098-1el5 with CentOS and the latest plugin download.

I managed to fix this by doing a chown and chmod. If that still doesn't work, re-compile the plugin as the user that is going to be running the znc, i.e. not root - and it should work.

Thanks for the info, but that didn't seem to be the exact problem for me.

My problem came from downloading the ZNC source, realizing I didn't have all the pre-requisites to build it, then just installing the packaged version through yum. When I went to download the colloquy plugin, the source file ended up being downloaded into the ZNC source directory. This allowed it to compile without error, and produced the crashing plugin.

I then tried a fresh download to the ~/.znc/modules directory and built from there, which gave me errors about missing header files for openssl and c-ares. I installed those development libraries, rebuilt, and everything worked.

Issue resolved for me.
