Hi Alexander,
Finally I managed to generate backtraces through the crashes occurred in
the recompiled version of Cantor. Again, I used the same expression, "2+2"
("2+2;" for Maxima), in Sage and Maxima backends.
Follows attached.
Regards.

The build is ok. You are almost done. I assume you did already 'make install' \
and everything was installed to /usr. Now you just need to do 'export \
QT_PLUGIN_PATH=/usr/lib64/plug<wbr>ins' to make your self-compiled binary aware \

/usr/local/lib(64)/plugins has to be used.<span class=""><br> <br>
