Is pressure grouting of a wall-crack, a good or potential solution?
It is a potential solution.  Buildings will settle and they usually do around 2-5 years of structure being built.  

The question is, is this normal structure settling or does this building have some issue that will cause it to move more.  It hasn't moved in the past year so I could really go either way with this.  

Pressure grouting could work.  It will allow very little movement but some.  The worst case scenario is you have hairline cracks a year or a few years later after doing this.  If water isn't an issue and you can live with the small cracks than I give this a strong maybe.

I would normally suggest going with an epoxy solution that would be stronger and have more flex.
