Description

(...the technique that keeps on giving)

I noticed that my user rule (contains adding user and adding a set of 3 ssh pubkeys) keeps getting "repaired" now.
It worked OK when I only had one key; after I extended it to add two more keys, it keeps adding the last one of them over and over again.

I applied the same update (server and agents) on the second lab now, getting coredumps there!

Version seems to not matter, i had it on:
rudder-agent-2.11.2.release-1.SLES.11
and:
rudder-agent-2.11.4.rc1.git201410170359-1.SLES.11

Also tried to see if it goes away if I add another key - > no.

replacing the existing key with random text made it not dump core.
number of lines also didn't matter.

Content is now like this:

just a test.
just a test.
and another line of testing.
just a test.
and another line of testing.

(source content is

just a test.
and another line of testing.

maybe this only happening because I'm testing with random text now. Coredump is with proper key anyway. :/

This is apparently triggered by the length of the key.

wc -c .ssh/id_rsa.pub
737 .ssh/id_rsa.pub -> is OK

wc -c .ssh/id_dsa.pub
605 .ssh/id_dsa.pub -> is OK

wc -c .ssh/id_dsa.pub
1119 .ssh/id_dsa.pub -> coredump

ok, i'm able to reproduce the issue; it's the class definition that fails.
