bcml 3.10.1: double free or corruption (fasttop)

[eku]

While I was pressing the button Browse the Merged Export Directory the programm terminated with double free or corruption (fasttop). It happens with BCML 3.10.1 under Linux. BCML 3.9.x worked.

Let me know if you need any further information.

The module that errored was PyQt5, but it errored under Python 3.8, not 3.10, according to the log. Can you verify whether it was 3.8 or 3.10 causing the issue?

BCML doesn't support 3.10, so that would be expected.

Also, any error that comes from PyQT code isn't really about BCML and should be investigated on their repo: https://github.com/PyQt5/PyQt
