The STIX Fonts Demo shows three Blackboard entries with the same font. In the 1.5.x line, these entries are italic, regular and bold. Additionally, the last three characters in the top row of circled numbers should be bold as well.
A bisect points to 4a2a186 as the first bad commit, the merging of #5214, so ping @zblz.

Yes, that should be fixed. Note it only happens with the mathbb style.
On a different note, the demo is called STIX Fonts Demo, but it doesn't actually use any STIX fonts!

Also: Second Fraktur and third Sans $\Phi$ should be bolded.

Note that setting mathtext.fontset : stix works fine in master, so it is likely a problem with the new DejaVu classes:
