Dear Maintainer,

A routine upgrade of evolution of Debian testing recently rendered evolution's memos unusable.

Evolution works as expected until the memos interface is selected.

Loading an old (from perhaps evolution 3.6) journal.ics also results in a crash.

Attempting to import the journal.ics does not work -- the import tool does not recognize the filetype.

Checking journal.ics with an online ics checker shows it is a proper ics file.

I can open the ics file in gedit and see all of my data.

Deleting the ics file from /.local/share/evolution/system/ allows for the memos interface to load and create new memos.

I have been unable to spot any problems with the ics file itself, but this seems like an unlikely source since the older ics file also fails to load.
