That does smell like memory corruption. A plugin writes to some memory
where it should not write to.
Depending where it writes to, different effects manifest: it can range
from "makes no difference" (or maybe just flip a red pixel on screen to
blue..) to "crash immediately".
It could also be some uninitialized variable, or it may be something
entirely different. gdb backtrace and or valgrind.org may be able to
shed some light.
Anyway, if you know which plugin causes the issue, best contact the
author or that plugin.
