   This is just because Akonadi keeps trying to restart. I'll attach a log   
   showing the first crash after upgrade, without the crash recovery attempt.

   I don't know why that is happening on my machine but not on Matthias's   
   machine, but it may be unrelated to this bug. That message also appears   
   when using the old version, which apparently works fine. I'll attach a   
   log of that too, for comparison.   
      
   For both logs, I've set log_warnings=10 in   
   ~/.local/share/akonadi/mysql.cnf and disabled AppArmor enforcement. It   
   doesn't look like there is a meaningful difference in the log files   
   before the signal handler is invoked.   
      
   I'm not sure why the included backtrace only goes as far as the signal   
   handler. I've added core_file to mysql.cnf and obtained a more   
   interesting backtrace with gdb.   
      
   "gdb-full.bt" is the backtrace as recommended by   
   https://mariadb.com/docs/server/reference/product-development/ma   
   iadb-fault-finding/how-to-produce-a-full-stack-trace-for-mariadb   
   #getting-backtraces-with-gdb-on-linux   
      
   Frankly, I can't comprehend that file, so I've also included a simple   
   backtrace for Thread 1, as "gdb.bt"   
      
   There does seem to be some hint of a cause in the backtrace - in 11.8.5,   
   get_schema_privileges_for_show() didn't call acl_get_all3(). See Thread   
   1, frames #9 and #10.
