OK, Looks like I can reproduce the crash, seem to happen when Input Mode uses
more than one layer. Perhaps due to output having less layers than input.
Also crashes on 4.0 pre-alpha 2 (pretty much expected):
krita.exe caused an Access Violation at location 00007FFC2E9E3DE8 in module
kritaqmic.dll Reading from location FFFFFFFFFFFFFFFF.

Crash location is probably
https://github.com/KDE/krita/blob/d6bfc136a743b2c30e72d8f76edccb3e2b027bc2/plugins/extensions/qmic/kis_import_qmic_processing_visitor.cpp#L73
The obvious mistake is not doing sanity bound checking on `m_images`, but more
probably needs to be done to handle the action properly (perhaps involving
layer deletion).
I don't know enough to comment.
