Hello,
thanks for the bug report. Based on the stack trace, this issue should be
fixed by the latest version from github, the one after Wednesday, 8th July
(git commit ID 028297f6cdc7ab6e9e233f8b944361c1e6da2ca0 ). The method call
from the snippet below is removed from the latest version.
In case the the source code and the build is newer than the date/commit
from above, then please let me know.
