Gmail's tab locks after reaching 100% usage

[gxtaillon]

After using any of the functions provided by the extension (sign, encrypt, encrypt & sign), the gmail tab where it was used locks shortly thereafter. Refreshing or closing the tab after that point crashes it and chrome displays the purple screen of death in its stead.

This is a clean installation, I have no idea what could be the cause.
Disabling the extension fixes it.

This sometimes happens with draft autosave prevention, it's something I'm actively looking in to. Did you have that enabled?
