(1.6 kB; text/x-patch)
Pd crashes in canvas_initbang() if you load a file that isn't really a patch,
because binbuf_evalfile() assumes the file is a regular patch that created a
canvas during evaluation. The fix is to check that the #X symbol is really
bound to a canvas before calling canvas_initbang() on its thing.
For an example of the crash:
echo oops > oops.pd
pd oops.pd
With the attached patch Pd no longer crashes and instead prints "oops: no such
object".
