3. Check recurrence preview. Save event and check the view.

Seems like this causes dataloss (except for users who know how to find the event in the unifinder).  --> Severity: Major or Critical?

This bug could likely be solved by updating to the latest libical. I remember seeing a patch that at some point stopped calculation if it had too many iterations.

Still exists in Lightning 1.3a1 + Mozilla/5.0 (Windows NT 6.1; rv:11.0a1) Gecko/20111213 Thunderbird/11.0a1. I get the error message shown below followed by different call stacks:

Error: uncaught exception: [Exception... "Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [calIRecurrenceItem.getOccurrences]"  nsresult: "0x8007000e (NS_ERROR_OUT_OF_MEMORY)"  location: "JS frame :: [...]/calendar-js/calRecurrenceInfo.js :: cRI_calculateDates :: line 537"  data: no]

Still existing. For me the engine of a calendar should be very trustworthy. Adding events like "The fifth wednesday every month" seems to be a rare thing of course, but the engine should be able to handle it stable! Disappearance of ALL events after adding things like this, makes me really feel ugly about the safety of my important appointments.

Does event really go "missing" to the user?

This bug has been corrected with the patch for bug 958974.
Since the unit test now has a specific test that creates a monthly event on a fifth weekday of February, I set the bug to fixed. I'd be glad if someone else could verify.
