Useless error-mesage "[ERROR] '(UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna'"

[htgoebel]

When running radicale --verify-storage I get quite some error messages like this, which - sorry to say - are no use:

[2021-01-03 21:29:41 +0100] [3411] [ERROR] '(UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna'

or

[2021-01-03 21:29:44 +0100] [3411] [ERROR] 'Amsterdam, Belgrade, Berlin, Brussels, Budapest, Madrid, Paris, Prague, Stockholm'

Expected result:
In the error message I'd like to learn

• what is the error - what is wrong
• in which file
• if the file contains several entries: which entry is the bogus one

Which Radicale version are you using? The problem might be with the config file /etc/radicale/config, or with older versions, the logging config file as well. Try setting the log level to debug for more info.

Radicale-3.0.6

Changing the log-level is not a solution, since the error-message should be meaningful.

I can't see how the meaningless text "'Amsterdam, Belgrade, Berlin, Brussels, Budapest, Madrid, Paris, Prague, Stockholm'" should depend on the configuration.

I suggested setting log level to debug to see what could've potentially led to such an error message, confusing thought it may be. Once we have a reproducible test case, maybe this can be classified as a bug and receive appropriate attention.

I'm afraid, I can't reproduce this anymore. Closing.

By chance I had the same error again, was able to reproduce it and tracked it down. It is cause bey vobject, see skarim/vobject/issues/174
