I'll try to fix this before 1.0 release, but there is no guarantee since till now I'm not able to reproduce the bug here.

I tested this repeatedly against the current code in git and encountered no crashes. I think it has been fixed.
If it's not, please open this bug again.

I believed that it has been fixed in our git repo previously.
I repeatedly test this part and can no longer reproduce the problem
So I'm now closing the bug report.

Please test the latest source code in our git repo.
If the bug still exists, please re-open the bug report.
Thank you very much.
