Pidgin, Word Documents, my Clipboard and I

Lately, I’ve experienced some weird Pidgin crashes when I was copy&pasting into chat windows. The strange part was: I didn’t even know what triggered the crash because I actually didn’t know what was in my clipboard at this exact point. This is a quick write-up of how I investigated the issue and some interesting properties I found out about clipboards.

Everything started with a document that I was editing in a Windows VM in Microsoft Word. At some point, I wanted to copy some lines of the document and paste it into a Pidgin chat window on my Linux host system. As I did this, I noticed that when I pasted the data into the chat window it included a lot of white spaces. I thought something went wrong and just tried to delete it by pressing CTRL+A (to mark everything) and press BACKSPACE. But this caused Pidgin (2.13.0-5 on Arch Linux) to close with a segfault and created a core dump.
