Comment 3 for bug 1443039

Crash seems related to changing the case in names of attributes stored in the patheffect definition in the <defs> section. Since this specific patheffect was never in a stable release version, it seems ok to me to commit breaking changes to such a "work-in-progress" path effect to recent trunk which are not fully backwards-compatible to earlier trunk builds. Path effects are not (or can't) be finalized with their initial first commit (changes are allowed as long as they have not been part of a stable release).
