**System Information**
Windows 8.0
Intel HD 4600
**Blender Version**
Broken: 2.73.6 12ed439
Worked: Before new proxy set up
**Short description of error**
setting proxies without enabling them crashes blender
**Exact steps for others to reproduce the error**
1. Open VSE
2. And a strip (I used Movie Strip)
3. Set proxies to 25%
4. Hit ok
Crash file only gives the leading to events but not the last so no help there
Here it is anyway though
