Becjk problem

Haiku x 64-bit is updated from hrev53640 ~ hrev53652.
Becjk cannot be input in QT5 software such as Qupzilla, Otter brower and LibreOffice.
Text files can be input.
No problem in Haiku x 32-bit.

This is almost certainly a recent regression in the qthaikuplugins, there was just an update to those. CC @diver and @3dEyes.
