Errors Due to Webmin RPM Size Increase

The Webmin package size has increased significantly in recent versions, from around 12 MB in 1.330 to 17 MB in 1.340 to 26 MB in 1.342 (development release). I noticed the following entry in the development change log:

Read User Mail
Removed huge un-necessary plugins and styles for Xinha.

However, after removing these plugins, the size increased (not decreased) by almost 10 MB! Is there something else huge and un-necessary in there that can be removed?

Due to this increase, the Webmin RPM will no longer install on two of my older (low-memory) systems. One of them actually fails with the following error:

# rpm -Uvh webmin-1.342-1.noarch.rpm
Preparing... memory alloc (4 bytes) returned NULL.

The other one just hangs on "Preparing" and consumes all available system resources (mainly swap) until eventually being killed.
