It helps to not have your toolkit override the default X error handlers
which print human-readable names, but that's a story for someone else.

For "request_code 146", since it's >128, it's an extension, for which
codes are dynamically assigned based on which extensions are being used
in your configuration - you'll need to run "xdpyinfo -queryExt" and look
for an extension line with opcode 146 to see which one that is.
