Calibre2opds 3.1 crashing, don't know why?

[Robotech_Master]

My Calibre2OPDS session is crashing. Can anyone help me figure out why?

Here's the log:

There have been a couple of reports of this, but so far we have not been able to reproduce it to determine the exact cause. It is reasonably certain it is data related in some way. The exception report in your case suggests it happens when trying to sort Series information.

There is currently an issue raised for this at http://calibre2opds.myjetbrains.com/.../issue/c2o-131. If you are prepared to let us have a copy of your metadata.db database so that I can try and reproduce it then please attach it to this issue (zipped if necessary to reduce size).

OK. For what it's worth, version 2.3 is working just fine.

Unfortunately there is such a large change between the source of the 2.x and 3.x series that it gives little clue to the cause.

Just to let you know that with your metadata.db file I can recreate the issue.

I will now see if I can identify exactly what is triggering the issue so that I can give you a short term workaround, and also whether the problem has already been fixed for the 3.2 release I am working on (and fix it if not)

Still trying to work out why the crash happens, but it appears that it can be avoided if you go to the Catalog Generation Options tab and uncheck the option to order by Series within the All Books sub-catalog (or suppress the All Books section completely).
