The captcha displayed while authenticating connecting to a tor bridge is unreadable

Steps:

1. Open "Tor Network Settings"
2. Select "Request a tor bridge from torproject.org"
3. Click on button "Request a new bridge"

The captcha displayed for verification on connecting to tor bridges is not readable. It has letters and characters merged in such a way that the probability of getting it right is very low(I have had a success rate of 1 out of 10 times).
