Session expired and no printed images after printing emails with in-body images

[es9465]

Hi,
I've found this problem on RoundCube 0.7.1, I don't know if previous version are affected.

1. Open an email with in-body pictures. No external pictures (linked to external site) or attached images.
2. Go to print message function, the one offered by Roundcube (not print function of the internet browser)
3. Print the message
4a. Printed email will not have any images (are printed on or more "X" and empty boxes)
4b. When you try to open another message with Roundcube (or to do any other operation), you will be logged out with "Session invalid or expired" error.

On roundcube log appears errors like this:
