Crash when used in combination with CtrlP

[netmute]

When I expand a snippet using the g:UltiSnipsExpandTrigger keys, then leave insert mode and trigger CtrlP, I get this error:

An error occured. This is either a bug in UltiSnips or a bug in a
snippet definition. If you think this is a bug, please report it to
https://github.com/SirVer/ultisnips/issues/new.

Following is the full stack trace:

I cannot reproduce. I tried this (with vim-snippets being tracked)

vim /tmp/filetype.py
iclass<expand trigger><esc>:CtrlPBuffer

can you provide a repro case?

[SirVer]

ping?

[netmute]

Sorry. I'm still trying to get this reproducible. I'm able to trigger the bug with the steps described above, but not every time. When I try that in a blank file, everything works. When working with an existing Javascript file it crashes.

[SirVer]

just let me know when you find a reliable way to reproduce. :thumbsup:

[netmute]

I think I have an example now. Open an existing file, for example this html: https://gist.github.com/netmute/04f5130c9d098a05bad8 Then expand the "input" snippet, go to normal mode and trigger CtrlP. It crashes every time for me.

[SirVer]

yep, that's it. I can reproduce now. I put it on my list to look into that, but I am a bit swamped right now, so no promises when I get around to it. Thanks for figuring this out.

[SirVer]

Should be fixed through an awful hack.

Great, thanks! :)
