This looks to be another case of the source application wrapping the TZID in double-quotes when using it in the VEVENT.

I get this error when importing:
WARNING: Can't find specified VTIMEZONE in VCALENDAR!: file /Users/mwillis/moz/trunk/mozilla/calendar/base/src/calICSService.cpp, line 719

I can't seem to find the bug to dupe this against at the moment.

[Michiel van Leeuwen (email: mvl+moz@)]

The first problem seems to be the quotes. The second is that in parsing the TZID= line, libical cuts everything starting at the comma. It claims it are multiple values.

Attachment: punch libical

I fixed the quotes-problem by working around libical oddities from our own ics service.
For the comma's, it seems that libical is correct by assuming they split different values. But only some properties can actually have multiple values. For all other properties, it should be safe to assume that the comma should have been escaped. I made libical do that. With that change, import is a little more error-tolerant.

[Michiel van Leeuwen (email: mvl+moz@)]

I just found out that the patch doesn't totally fix the bug: after a restart, the item is not shown anymore. I imported it into an ics calendar. The file still has the item, it's just not displayed anymore. I don't know yet why. Maybe it has to do with foreign timezones.
But still, the patch should at least fix part of the problem.

> +    *end = (char*)(size_t)line+length;

IMO no casts at all are necessary here. Casting variable line to size_t then back to char * makes no sense (cast-operator takes precedence over +).

The rest looks good, r1=dbo.

I am still seeing this bug in Lightning 0.3.1, released Feb 19 2007.
Incoming event from outlook has following DTSTART:
DTSTART;TZID="Greenwich Mean Time - Dublin, Edinburgh, Lisbon, London":2007
 0508T173000

Importing this fails with failure code 0x80004005 (NS_ERROR_FAILURE)[calIIcalComponent.startTime]

Changing the TZID for DTSTART and DTEND to "/mozilla.org/20070129_1/Europe/London" allows event to be imported.

Phil, this patch was not checked in to SUNBIRD_0_3_BRANCH (where Lightning 0.3.1 comes from). The bug is fixed in the next major release, i.e. Lightning 0.5.
