I noticed the problem again today. Thunderbird had been started on Saturday and so it has failed relatively quickly this time.
The add-ons: Lightning Adblock Plus Enigmail LookOut (for TNEF attachments) Mail Merge TBDialOut Looking at the console I see things like this: Warning: CalDAV: No response status doing multiget for calendar daniel2 Warning: CalDAV: Get failed: CalDAV: Error: got status undefined fetching calendar data for daniel2, null Warning: There has been an error reading data for calendar: daniel2. However, this error is believed to be minor, so the program will attempt to continue. Error code: 0x80004005. Description: CalDAV: Error: got status undefined fetching calendar data for daniel2, null Warning: There has been an error reading data for calendar: daniel2. However, this error is believed to be minor, so the program will attempt to continue. Error code: READ_FAILED. Description: Is there a way to enable timestamps on the console output? The CalDAV server is Davical on Debian. There is nothing in the server-side error.log file. Regards, Daniel
