Comment 6 for bug 791061

I know this is a somewhat old bug, but I'm affected by it when using Linux Mint 13 (AMD64). I am, however, trying to make Firefox default, rather than Chromium.

So, here's how I ran into it:
1) Install LinuxMint Mate edition.
2) Install other programs I like, such as WINE, Samba, etc., including adding the WINE repository from WineHQ.org.
3) Use the system for a month or two; sorry I can't be more specific on this point.
4) Install Chromium browser via synaptic. I didn't use a 3rd-party repository for this.
5) Set/install Chromium settings/extensions how I like them. I'm using Adblock Plus and Web of Trust, plus whatever media plugins web sites request.
6) In Firefox settings, tell it to check to see if it's the default browser on startup; disable this option in Chromium.
7) Note that FF never asks to set browser at startup.
8) Click on a link in a program--Pidgin, Virtualbox, whatever. It opens in Chromium.

Sadly, I can't say which of the above are involved in the problem, or that I know all the relevant details. Items 1, 4, 6, 7, and 8 are definitely involved, though.

I managed to work around this problem/bug with the following:

sudo update-alternatives --config x-www-browser
(select the appropriate option)

One forum suggested that the symlink, /etc/alternatives/x-www-browser sometimes needs to be manually moved/deleted in order for the above workaround to function properly. This wasn't the case for me, but I thought I'd mention it, anyway.

Thanks for your interest in fixing this bug!
