System Information
64-bit Fedora 22 and NVIDIA ION

Blender Version
Broken: 2.76 dd185bf (local build from git with debug info)

Short description of error
Blender crashes with segmentation fault when showing hidden objects with alt+h.

Exact steps for others to reproduce the error
Exact steps to reproduce are still bit unclear, but seems to happen quite easily when editing my current project and has always occurred after pressing alt+h.

Here's a full backtrace of the segfault:

Line causing the segfault is here:
(gdb) list
1631 bGPdata *gpd = CTX_data_gpencil_data(C);
1632 Object *ob = OBACT;
1633
1634 if (((v3d->around == V3D_AROUND_ACTIVE) && (scene->obedit == NULL)) &&
1635 ((gpd == NULL) || !(gpd->flag & GP_DATA_STROKE_EDITMODE)) &&
1636 (!(ob->mode & OB_MODE_POSE)))
1637 {
1638 copy_v3_v3(rv3d->twmat- [x], ob->obmat[3]);
1639 }
1640 else {

As ob is NULL, it's the ob->mode reference.

According to git, the ob NULL check was removed in Grease Pencil: Merge GPencil_Editing_Stage3 branch into master commit
