hello,

so I am getting these sporatic runtime errors when I run a program (using opencv) in ubuntu, but i dont quite know what it means. here is the error:

fovea: /build/buildd/cairo-1.8.8/src/cairo-surface.c:1670: _cairo_surface_fill: Assertion `! surface->is_snapshot' failed.

what does this mean? in addition, I am getting segfault errors that i just cant pinpoint, they seem really random. does anyone have any ideas? thanks!
