Augh, can someone do something about those "WARNING **: Inkscape currently only supports color-interpolation-filters = sRGB" messages? They're clogging up my console while I'm trying to get other bug messages. :( (but all my text tool problems are gone, yay!)
Anyway, sorry for the delay.
This is weird, because it is exactly these two things that I fixed! Can you send me an example file?
Still Inkscape 0.48+devel r11297.
There are two files attached: - The New doc file is the first file that crashed when I was testing Powerstroke. In fact, even now, it crashes Right when I open it. :P Which is rather fortunate because I wasn't able to get a second file that crashed once to crash again, nor the Tests file. - The Tests file is my more systematic attempt to reproduce the error messages. I basically started with the same-ish shape for different algorithms and cusps and attempted to torture the lines until I got a proper error message.
In particular, I've marked one shape where it was quite easy to reproduce this error message: WARNING **: Exception during LPE [Unstable!] Power stroke execution. lib2geom exception: Invariants violation (./2geom/piecewise.h:144)
Just select with the F2 tool, and drag the diamond back and forth between where the two lines point at.
The error message should pop up. I was able to reproduce that error in several other lines but not as systematically. It seems to affect mostly the Linear and Spiro algorithms, though it may affect other line types too. It usually happens when editing the powerstroke width.
No matter what I did though, I wasn't able to reproduce a crash in this session (and not for lack of trying).
