Certain messages, whenever I click on them to view them, Claws crashes. Backtrace attached.
works for me. try with the latest release, re-open if it still happens
* The backtrace is kinda strange. Which one is the crashed thread? Thread 13? That's very deep in the LabVIEW runtime library.
* Since you sound as if you can reproduce the issue with the HTML message(s) you refer to, can you make available such a message? e.g. attach it here unmodified?

This one seems fairly consistent. I'm running Ubuntu 14.10 with KDE frameworks 5.

Emphasis on "seems". The attached message is not sufficient to crash Claws Mail 3.11.1 running on Fedora 21 (x86_64).
Well, your project, and you can do as you wish, but I just went back to double check, and click on message . . . crash *again*.
I've tested on ubuntu 14.10 and KDE 4.14.1 and don't get a crash.
I don't claim that it doesn't crash for you. I just point out that the attached mail is not a sufficient test-case for Claws Mail 3.11.1. That also implies that you may want to update and try to reproduce with that newer version, although there is no conclusion that only 3.10.1 would be affected.
You may need to do more trouble-shooting to collect data and find out what's wrong with your runtime environment (i.e. the dependencies you've built with). You have yet to reply to the first part of comment 2.
Btw, I'm not a Claws Mail developer.
