LP:942283 - MariaDB crashes on import from MySQL mysqldump export

So in the process of moving to a new VPS (fancy name for a VM) with MariaDB installed (Ubuntu 10.04 LTS, stock MariaDB, whichever one is the latest in the apt sources), and when I try run the .sql export on my MariaDB installation I get the following:

root@primary:~# mysql -q -u root -p prod_test < dmp.sql
ERROR 2013 (HY000) at line 1529: Lost connection to MySQL server during query

Line 1529 is quite innocuous: /*!40000 ALTER TABLE `tblSubscriptionEmail` ENABLE KEYS */;

This is consistent and reproducible. Since MariaDB errors out to syslog, I checked my syslog to see what it had to say, and here it is:

What gives? Is it a memory leak that's causing the process to be terminated? I'll gladly give up a copy of the 44mb MySQL dump, but I would have to do so privately for privacy concerns.
