HSTracker Crashes when queuing into an opponent that is masking its name (Your Opponent)

[ShereKahn]

Description

since the version prior to 3.1.9 (3149), I have seen multiple crashes of HSTracker on the standard ladder (the only mode I play) when queuing into an opponent that is "anonymous" (I think this is when the person is logged into battle net with the "appear offline" option).

Here's the log of this morning (arount 10, restarted HST a couple of times) then reopened it to write this report.

Here's the log:
hstracker.log

the crashes reports from this morning
HSTracker-CrashReport.zip

and a screenshot (hopefully it helps clarifying what I meant by "anonymous" above):

having had a quick look the crashreports it seems that the recent hearthmirror update may be linked to the issue:

Thanks for the report. I will take a look next week as I hope to have time to investigate it properly.
