This has sometimes happened (to a lesser degree) on various projects I’ve participated in, including Exaile. I used to volunteer as bug triager in another project, and this was the kind of thing that would wreck your mood for the rest of the day—even for someone whose role was not to fix bugs.
So don’t. Pinging developers on IRC every once in a while may be OK, especially if they’ve expressed some interest in the bug. Adding useless comments to a bug report is counter-productive, because it buries important information under junk.
