Whenever I load the packages breqn and icomma into the same document, the document fails to compile. The order of the packages makes no difference. MWE:

raises the following cryptic error:

but compiles if either of the packages are commented out.

I could not find anyone else with this problem. Does anyone know of a workaround, or if not, who should this bug be reported to (I've never reported a bug to a package manager before)?

  As you might have guessed, I was using icomma before I tried using breqn, and after removing icomma for this specific document, I found that breqn also requires restructuring every single occurence of a_textx in that document – so I probably won't be using it after all, easier to manually set line breaks...

It isn't really a bug. breqn by design has to re-implement almost every aspect of math processing and as documented is thus incompatible with more or less any other math mode definitions that are not explicitly written to work with breqn.

Really breqn is an unfinished experiment and sadly its original author died some years ago, and so it is probably not really recommended for use in a production document unless you have very tight control over the input and know it works well on that input, some large but regular output from symbolic computer algebra systems fall in this category.
