After installing the latest Version 2.12 (b136) 64 bit my Google Tasks list disappeared and I tried as explained to add it again in the Options Menu. After entering the Google login data and password, for a fraction of a second the authorization screen appears and then crashes with a segfault (no chance to push the accept button). After that the add button for adding calendars in the option menu does not react anymore. After the crash other option settings can't be changed either (all the button don't react). Please help! Thanks.
P.S.: I add the screenshot just before the crash occurs (it's in Spanish but pretty self-explanatory).
