Here's how to reproduce it:
1) Open Rosegarden and record a MIDI segment about 100 measures in length
(I've also had success in the 80-90 range).
2) Click the "New" icon to start a new project (no need to save the old
one).
3) Record a short MIDI segment (13 measures is what I tried). When you
stop recording, the length of the segment may be anywhere between 90
measures and up, and may or may not include some data from the session
recorded in step one.
I have attached an example file for your reference, you can see the bit
that I recorded through measure 13, then a lot of space, and then MIDI data
again at measure 82 (which is part of what I recorded in the previous
unsaved session).
NOTE Please see original bug report [#1201] for link to example file.
Old bug #2284925 is now [#1201]. Same title as this one.

I can't reproduce this. 10.02 doesn't build anymore with modern gcc. I think this one was fixed at some point over the past 5 years. Time to move on...
