Dear Users, has anybody succeeded to run sasview 4.1.0 on Ubuntu/Debian? I downloaded, built and installed the current source code versions for sasview + sasmodels from github. I can start the program, load data and specify fitting models (e.g. sphere model and using a polysphere example data set coming with the installation), but as soon as I start the fitting the window freezes and the whole application quickly terminates with a segmentation fault. I have the same problem on Ubuntu 14.04 (wx 2.8) and 16.04 (generally higher version numbers for the dependencies, wx 3.0). Thank you in advance, Martin p.s. I installed the dependencies listed on http://trac.sasview.org/wiki/LinuxBuildDependencies via Ubuntus package manager and pip. In case of the Ubuntu 16.04 installation, using "python check_packages.py" the following installed dependencies are listed: Checking Required Package Versions....
