Update:
Reproducible: 4/4

More accurate steps:
1. Select "I want to review/modify my disk..."\
2. Change Partition scheme to "LVM Thin Provisioning"
3. Continue
4. In "New Fedora 20 Installation" click "Click here to create them automatically"
5. Select / (fedora-root) and "-" to remove

Works fine for /boot (partition) and swap (which is plain (linear) LV)

I am using TC5 (anaconda-20.25.1-1) and have been unable to reproduce the reported failure. Please try with TC5 and see if the problem persists.

Still the same I think - opened BZ 1022366 so abrt catches duplicates.

When I created other mountpoints (thin LV) those could be removed.
I removed swap on the VG and then removed root LV just fine.

I created LV /home and thin-LV /, attempt to remove / resulted in crash.

Seems that happens only when there are other non-thin LVs.

I was able to reproduce it. It happens when you remove the last thin lv from a new/non-existent pool. I'm testing a patch.

My test of the patch was successful. Please try it for yourself to verify:
