The relevant frame is

#9 0x00007f54370cb59b in tesseract::OpenclDevice::HistogramRectOCL(void*, int, int, int, int, int, int, int, int*) () from /usr/lib/libtesseract.so.5

So yes, this is a tesseract crash. If you can also reproduce it with the command line tesseract executable, please file a bug to tesseract.

Righto, I'll inquire elsewhere. Thanks.
