Just trying out the new “search for all missing episodes” feature. After clicking the button I get a popup saying [missingepisodesearch] failed. The log gives the above error with:

Could you run mono with --debug mono --debug /path/to/NzbDrone.exe it will give me some more information so I can track it down.
Sure, give me a little bit
Here you go:

I’m having the exact same issue with the same output when executing “mono --debug /path/to/NzbDrone.exe”. It’s always good to know that this might not be a random isolated issue.
Hey JuggalotusHEat and Simonk83,
Can you guys tell me which OS you are running? Just trying to see if there are any further similarities.
@neckris OS won’t matter, its caused by multiple images for the same season (banner and poster) as well as another for multiple series images (banner, poster and fanart).
I just pushed a fix to develop and its ready for testing, it would be great if it could be tested by one or more of you. For Windows: https://github.com/NzbDrone/NzbDrone/wiki/Release-Branches
For Ubuntu you can change the source of the deb packages to develop by changing the url (change master to develop)
For Linux/OS X you can grab the appropriate build from: http://update.nzbdrone.com/v2/develop/
I should be able to try in a few hours from now, I’ll let you know!
Just tested it with “develop” build. Output is

fyi I did notice that the logs on the web gui now show the error occuring “TaskExtensions| Task Error: Object reference not set to an instance of an object”, which it didn’t before (only in the mono run through terminal).
Also tested on develop build 1297, similar error as above http://pastebin.com/wbe1MLwn
Whoops! got my threads mixed up and fixed a totally different issue and left this one in there… I’ll take a look, sorry
EDIT: Should be fixed now, take a look at 1298 and let me know, please.
Looks good at 1298, MissingEpisodeSearchService ticking through all series now - thanks!
Yep, confirmed as working for me. Thanks for everything @Markus101 !
I probably won’t get a chance to test today, but it sounds like I don’t need to anyway. Thanks Markus 
1298 fixed it for me. Thanks!
