bug#69122: openmolar@1.1.6-g81838c85 runtime issues

[Marco Rimoldi]

Hello,

package builds and installs, but crashed when started.

Issues are mostly related to PyQt5 methods expecting integers instead of 
floats, raising errors when true division is involved.
 
Work so far has been proposed for integration to upstream in this pull request:

https://github.com/rowinggolfer/openmolar1/pull/261

Another standing issue appears to be caused by the python-mysqlclient@2.0.1 
package See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=69064 for details on 
that.
 
Cheers,
Marco
