After updating my Ubuntu desktop to a more recent release (12.04 / Precise Pangolin), my rarely used Canon Pixma MP190 stopped working. Not completely, but in a rather annoying way: Printing a single page works fine, but printing multiple pages / copies causes the printer to hang. Hard. As in, you have to pull the power plug to reset it, as no button will do anything anymore.
Apparently there was a bug introduced with CUPS a while ago, or rather a change in behavior of CUPS which triggers a bug in the printer Firmware. Took me a couple hours to find and had me on the brink of throwing out the whole printer.
And it looks like it affects quite a few other USB printers as well: Epson NX130, Canon i550, i560, ip4200, ip4300, ip5200, MP180, MP160, MP210, MP450, MP500, MP520, …
To save you from reading through all the comments: Till Kamppeter came up with a workaround that worked perfectly for me and others.

Namecheap currently offers one of the most affordable ways to get a (not self-signed) SSL cert to use with your web-/mailserver – the only drawback being, that it isn’t signed by a CA Root, but through some subsidiaries, which means you’ll also have to install a supplied CA bundle on the server or else you’ll get a bunch of SSL errors.
With dovecot as POP/IMAP server, that’s actually quite easy – just put all the certs in single file, starting with your servers cert and followed by the three certs supplied by Namecheap/Comodo.
This should work fine with most mail clients, like Thunderbird or Evolution. The cert also worked with Apache for HTTPS. But for some reason, it didn’t work with my Android mail app.
Turns out, Android can be quite picky about the order of the cert chain…

After installing the Honest Hearts DLC for Fallout New Vegas, all of the sudden the in-game sound stops working the second I load a savegame. Running FalloutNV.exe from the console, I get tons of these as soon as the game goes mute:
