Panda is crashes very often

Testing version:
1.0 (532)

What were you doing:
Typically on document saving, but sometimes on window close.

What feature did you use:
Just text editing, sometimes inserting text from the buffer.

What happened:
After inserting some text from the buffer, or after pressing cmd+s shortcut Panda is crashing (interface isn’t responding).
Probably important: I’m trying to edit .md files but in result (after crash) I have .textbundle instead with inside and info.json with next content:

  "version" : 2,
  "type" : "net.daringfireball.markdown",
  "transient" : false

What did you expect to happen:
Stable work :slight_smile:
