ikhal won't delete single instance of recurring event

[esthet1cs]

When trying to delete a single instance of a recurring event, ikhal throws an error after being closed and the instance does not get deleted. Deleting all instances of a recurring event works fine.

• open ikhal
• move cursor to instance of recurring event
• press d
• choose single instance in the delete menu that pops up
• instance is now marked with a small letter d on the left
• close ikhal

ikhal throws the following errors:

The expected behaviour would be that the single instance of the recurring event marked as deleted is deleted, like a regular event would be deleted.

[WhyNotHugo]

There were some fixes related to deleting a single instance in a recurring event some weeks ago.

Your version of khal is pretty old, can you try with the latest release?

Thanks for the info - that worked, the problem has been fixed. And I have learned for next time to try this before opening an issue here. The fix just hasn't made it downstream into the Debian package yet.

I installed khal from the repo into a virtual environment with pip install git+https://github.com/pimutils/khal. That got me version 0.11.3.dev37+g21ee686 . Deleting a single instance of a recurring event works. Thanks again!

Edit: Debian Unstable already has the latest version 0.11.2 that should include the fix.
