Ok, don't worry too much then. I don't think it's a great problem as there's a
workaround.
What I did in the meantime is to use ogr2ogr, a QGIS command-line tool, to
reproject the shape file.
If I recall correctly, the invocation was
$ ogr2ogr -f "ESRI Shapefile" -t_srs EPSG:4326 dst/ src/original.shp
Then I used QGIS to recreate the spatial index and added the result to my
GeoServer's shapefiles directory. After recreating the layer the bounding box
was fixed.

I get the same results from cs2cs.

But just in case, I'm using QGIS OSGeo4W 2.8.7-1 x86_64 for Windows.
Thanks,
