Ted:

I realized I could avoid the gnome-keyring problem, and also avoid any risk to my main development environment by installing it in my backup development environment, which is is an Ubuntu 12.04 partition. 

I installed Rosegarden 12.12 there without any problems - congratulations on your straight-forward, accurate, and detailed instructions.  The make did take quite a long time, and I was glad I had a gigabyte of RAM (or it might not have succeeded in the link step, which used over 75% of my memory space. 

I was going to first reproduce the problem with the installed version to be thorough, but being eager to try it, I fired up qjackctl, qsynth, my MIDI device, and the version of Rosegarden just built (12.12). 

I set it up to record into two tracks using the recording filters, and recorded the piece which has exposed the problem. 

To my pleasant surprise, at the end of the recording (when I clicked on "Stop"), there was no hang, and everything seemed okay. 

When I played back the recorded piece, I noticed it occasionally missed one or two notes of one of the chords played, which it has been doing using my work-around method of recording. 

So I deleted the two segments, and repeated the recording process.  Again, at the end of the recording process, there was no hang.  I played it back, and although it again occasionally missed notes of some chords played, it missed fewer of them this time. 

Knowing this problem does not always occur, I decided to try it again. 

This time, at the end of the recording (when I clicked the "Stop" button), the Rosegarden window was unresponsive, suggesting a hang. 

In my terminal window, I saw it had indeed crashed. 

I copied as much of the diagnostic information as was available in the terminal, and pasted it below:

To make the Rosegarden window go away, I had to kill it using the system monitor. 

I can send you the core dump, it it can be useful.

   Ok, finally got some time to look at this.  I was unable to reproduce 
the hang.  I suspect that this was fixed back in January.  We might be 
able to work on getting that patch into Ubuntu.  In the meantime, can 
you grab the 12.04 source, build it, and retest?  That should fix the 
hang.  Let me know if you need any help getting it built and running 
it.  My process for doing this is on the wiki:

http://www.rosegardenmusic.com/wiki/dev:eclipse

   That gets the latest svn, but you can expand the tarball and start 
with "Get Dependencies".  When you get to "Install Eclipse", stop and 
type "./rosegarden" to run what you built.

   Let me know if you need any help and I can walk you through the 
process.  We've still got some more bugs you've identified to work on, 
so if we can get you running the latest (from svn), we can collaborate 
on getting them fixed.  Then we can look into either a PPA for you, or 
sending patches to Ubuntu which should work their way into lubuntu.

Ted.
