[Lazarus] Lazarus on Debian "Wheezy"

[Mark Morgan Lloyd]

Using FPC 2.6.4 or late 2.7.1, compiling trunk on Wheezy is OK but 
running gives me

The program 'lazarus' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
   (Details: serial 428 error_code 188 request_code 155 minor_code 23)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the --sync command line
    option to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error() 
function.)

Appears to affect Athlon (32- and 64-bit) and Intel (32-bit, don't have 
64). Does not affect Squeeze. Building with OPT='-O- -gl' still doesn't 
allow me to get a bt.

Suggestions, anybody?
