Crash when attempting to snarf text on Windows 10

[atilde]

edwood is crashing when attempting to snarf text on Windows 10.

I just build the application from master today.

Here's the entire log, from startup to crash.

I have changed the clipboard code lately. Does this replicate with the last released version?

[atilde]

The last release works as expected.

@ahedgewitch: as a consequence of fixing #331, I changed the snarfing code in pr #449. Does this still replicate as of c891388? If so, can you provide me with some more details on how to replicate?

[atilde]

I cloned the latest code (c891388) and it is no longer crashing when attempting to snarf or paste text on Windows 10.
