Hi ,

I am having some issue with vmd 1.9.2. As soon as I open a file (the
first example in the tutorial) there is a crash. I am pasting a stack
trace and the output below when running: vmd -debug. First I tried the
binary from the vmd site, then I tried building form source, but the
crash is the same. Any idea what is going wrong here?


$vmd -debug
