@mapellidario FYI, this already second glitch we found in current WMCore, shall we start out own branch and merge when @amaltaro is back ? Or i @todor-ivanov comfortable with merging such fixes in current master ?

Hi @belforte , Thanks for reporting this!

I'll take a look into this ASAP. I feel comfortable enough merging a fix of the sort, the only problem is this is not going to make it for the December release, which is about to be deployed tomorrow.

Do you have a fix already in place or should I work on it myself?

p.s. Just one more thing which is worth keeping in the issue would be a dump of an exception or an error message (in case you have one at hand).

don't worry @todor-ivanov it is a trivial change. It is simply a matter of our branch vs. your master vs. your tag etc. You should leave it to @mapellidario to make PR's

[todor-ivanov]

ok @belforte, waiting for the proper PR then. Thanks!
