Hi all,
First time poster, long time lurker and Kodi (XBMC) user
I'm using Kodi nightlies for couple of years already (updating once or twice a week) and had only really good experiences with stability so far. Amazing job everybody on Kodi team!
Recently however Kodi started to crash every time I turn off my TV and receiver. My Mac Mini is hooked to a receiver through HDMI and never shuts down.
For a while I did not have time to look into this further and I just kept updating hoping the crash goes away. It did not stop, therefore I looked into this a bit more.
It seems like the recent (23 days old) change c2d14c7 in /windowing/osx/WinSystemOSX.mm introduced display name query, but does not perform nil pointer check.
This looks like something which could easily cause crash if the HDMI is lost (receiver shuts down) and primary display is not available anymore.
I'm including the crash callstack which shows that nil/null pointer exception in string creation is indeed happening:
For completeness I'm also including my debug log file, but it's rather uneventful - http://pastebin.com/2xMLfWXM
Hope this helps to fix the problem quickly. I'm available for testing if necessary.
cheers,
