Created by: ghost

Fails on both 1.04 and master branch

Steps to reproduce:

1. Click Add Earlier Activity
2. Enter "10.0@ABC" in the activity field
3. Enter "Hello World" in the description field (any text will do but must be longer then one word)
4. Click Save

Expected result

1. The activity and the description should be saved correctly

Actual result:

1. The activity field has the second and subsequent words from the description field entered in step 3 above
2. The description is blank
