# Known issues¶

When using Glue with the PySide bindings, the following error sometimes occurs for some MacOS X conda users:

Qt internal error: qt_menu.nib could not be loaded. The .nib file should be
placed in QtGui.framework/Versions/Current/Resources/  or in the resources


This is due to the PySide conda package in the defaults conda channel being broken (see the following issue for the latest status on this issue). The workaround is to either use PyQt instead of PySide, or to use the PySide package from the conda-forge channel:

conda install -c conda-forge pyside


## Undefined symbol: _ZNK7QSslKey9algorithmEv¶

On certain Linux installations, when using Anaconda/conda to manage the Python installation you are using for glue, you may run into the following error when launching glue:

ImportError: /usr/lib/libkdecore.so.5: undefined symbol: _ZNK7QSslKey9algorithmEv


This should be resolved in recent versions of the PyQt conda package, so updating to the latest version should be sufficient to resolve this issue:

conda install pyqt
