That is sort of strange in itself, given that there are essentially no
changes between 0.10.1 and 0.11.0 in that part of code. The test suite
also includes complex-valued test problems for gmres, so it not crashing
is also not immediately understood.
If the crashing version was 0.9.0 or earlier, then I'd understand what
is going on... If you still can, double-checking what
'print scipy.__version__' said could be useful.
But nice to hear it works now. (And for future reference, PyAMG contains
pure-python Krylov solvers, including gmres.)
