[Lazarus] Lazarus crashing reproducibly on startup (64-bit Linux)

For anyone still interested in this thread, sorry it's taking me so 
long to post again but I'm on a satellite internet connection, I only 
have unrestricted downloads between 0200 and 0700, and so it takes me 
quite a while to set up virtual machines and do the updates.

While I've had one reply from a posting to the Mint Debian forums from 
someone who is tracking the unstable repositories and is able to run 
Lazarus without a problem, there seems to be no doubt that there is a 
basic incompatibility between Lazarus and either the stable or testing 
distros of Mint Debian. I haven't been able to get Lazarus to start on 
either distro, whether 32 bit or 64 bit, but plain Debian stable or 
testing runs Lazarus just fine.

I'm going to try pointing at the unstable repositories now, and I'll 
post again in 3-4 days when I've had time to do the final set of 
updates and try all the different permutations.

For the moment, I strongly advise anyone who wants to run Lazarus 
*NOT* to install Linux Mint Debian. If you want a rolling distro, 
stick with plain Debian rather than the Mint version, or try one of 
the others.

All of the above does NOT apply to the Ubuntu-based versions of Mint. 
They run Lazarus without problems, too.
