When running it in gdb, I get the following backtrace:
Starting program: /usr/bin/apt-cache search apt
^C
Program received signal SIGINT, Interrupt.

So it looks like the iterator used to get translated descriptions causes this.

This gets triggered by the following configuration:
% cat /etc/apt/apt.conf.d/20notranslation
Acquire::Languages "none";
