I can confirm this crash when using GDB and the following steps:

1) open showFoto, Liquid Rescale
2) set some width or whatever parameter
3) set breakpoint at dimgscale.cpp:156
4) when breakpoint is hit, set scaleInfo->xup_yup == 0 (to simulate the above
backtrace)
5) resume GDB
6) it will crash

Either xup_yup=0 is always invalid in this case and something set this to a
wrong parameter, or the code in dimgscale is wrong.
Maybe different xup_yup values will give different crashes?
At least it shouldn't contain 1,2 or 3, to reach the else path where the above
crash happened.
