Comment 11 for bug 207798

I also couldn't install any .deb file.
Here's what I did though:

1. Removed libglib1.2ldbl (it conflict once you actually get a libglib working)
sudo apt-get remove libglib1.2ldbl

2. Grabbed an rpm of libglib1.2 from http://rpm.pbone.net/index.php3/stat/4/idpl/4337058/com/libglib1.2-1.2.10-16mdk.i586.rpm.html (did a quick google, any release should be fine, I chose this one)

3. Alien'd
sudo alien libglib1.2-1.2.10-16mdk.i586.rpm

4. Install with gdebi
sudo gdebi libglib1.2_1.2.10-17_i386.deb (no idea why -16 changes to -17)

5. Grabbed notes
sudo apt-get install ibm-notes-framework

A rather nasty way to have to get around it but it works.
