Tested on pencil 1 (build 6)

When exporting a page to PNG the PNG extension is not automatically added to the file name.

Reproduce: 1. click Document menu 2. export page as PNG 3. enter file name (without extension) 4. click Save

Result: file is stored without extension.

Additional comment:

This only happens when a page is duplicated. When creating a new page the export works fine.

I have the same issue in every version of Pencil (1.0, 1.1 and 1.2), but happens always, not only when page is duplicated.

it is no compatible with the firefox18,download the xulrunner http://ftp.mozilla.org/pub/mozilla.org/xulrunner/releases/16.0.2/runtimes/xulrunner-16.0.2.en-US.linux-x86_64.tar.bz2, and unzip to the /opt directory, then editor /usr/bin/pencil change /usr/bin/firefox to /opt/xulrunner/xulrunner, the issue can resolved temporarily!!
