Why am I unable to load any (user created or shipped with MATLAB) MAT-file in MATLAB 7.10 (R2010a)?

I am unable to read any MAT-file, it does not matter whether I just created the file myself or whether I try to open a MAT-file which was shipped with MATLAB; for example:

load clown

 ??? Error using ==>  load

 /usr/local/MATLAB/R2010a/toolbox/matlab/demos/clown.mat

 File may be corrupt.

This also leads to the following error when trying to create a figure:

 ??? Error using ==>  load

 /usr/local/MATLAB/R2010a/toolbox/matlab/uitools/dialogicons.mat

 File may be corrupt.

This issue can be caused by having an older MATLAB or MATLAB Compiler Runtime on your LD_LIBRARY_PATH. Please try starting MATLAB after clearing (or at least removing the older MATLAB versions from) the LD_LIBRARY_PATH.

If this resolves the issue, you could modify the MATLAB start script ($MATLABROOT\bin\matlab) to correctly (un-)set the LD_LIBRARY_PATH before starting MATLAB.

I deleted the other matlab instance and and copied my old simulink file that wasnt broken from a previous commit - thanks git!
