Google calendar crashes with start/end date set

[vestingz]

I am using vdirsyncer v0.16.0, Python 3.6.2 on Arch 4.12.3-1. I set up a pair for syncing between my local calendar and the calendars of my organization hosted by Google. Discovering the collections (vdirsyncer discover) works well, as did the sync, at least for the first time. Since then I have been trying to sync this pair without any success; vdirsyncer returns "Unknown error..." (see debugfile).

Here is my (sanitized) config:

status_path = "~/.vdirsyncer/status/"

[storage calendar_remote]
type = "google_calendar"
read_only = "true"
token_file = "~/.vdirsyncer/token"
client_id = "<SOMETHING>.apps.googleusercontent.com"
client_secret = "<SOMETHING>"
start_date = "datetime.now() - timedelta(days=10)"
end_date = "datetime.now() + timedelta(days=100)"

[storage calendar_khal_loc]
type = "filesystem"
path = "~/.calendars/calendar_khal/"
fileext = ".ics"

[pair calendar_khal]
a = "calendar_khal_loc"
b = "calendar_remote"
collections = ["from a", "from b"]
partial_sync = "ignore"
conflict_resolution = "b wins"
metadata = ["displayname"]

and the error log:
out0.txt

Edit: I did some more testing and it seems that deleting everything in ~/.vdirsyncer/status/ helps.

Ok, since you deleted the data I can't help figure out what the issue was, but it appears that there's a bug in vdirsyncer... somewhere.

[vestingz]

No problem, I can upload those files somewhere, as the bug reproducibly appears after running vdirsyncer the first on an empty status directory. It then creates those files again and fails with seemingly the same error the next time I run it. Which files exactly would be helpful?

[untitaker]

The .items file would be useful (in addition to the debug logs)

[vestingz]

I will send you the .items file to your personal email, as they contain information I'd rather not share publicly. Please also find the debug log in the original post (out.txt).

[untitaker]

@vestingz I can't decrypt the email you sent me. It appears to be encrypted with the wrong public key.

[untitaker]

Hmm, the status file you sent me didn't help. I also don't understand how you get the error you're experiencing, regardless of the server's response it should be impossible to get into this state.

Could you try to remove your timerange parameters?

[vestingz]

Yes, removing the timeranger parameters helps indeed. thank you :)
This, however, bloats the calendar files as the calendar goes back to 2011..

I don't think this is ready to close yet... needs further investigation.
