IDE uses bootloader folder name rather than upload protocol to determine upload protocol

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In "boards.txt" change bootloader.path value for any board using the avr109 
USB upload protocol to anything but "caterina".
2. Attempt to upload a sketch to that board.

What is the expected output?
Arduino IDE should report that it changes the baud rate to 1200 and 
opens/closes the port; then it should wait until the current port disappears 
from the port list and a new one appears. It should use the new port to upload 
code to the board via avrdude.

What do you see instead?
Arduino IDE immediately attempts to upload code to the board without first 
activating the bootloader. avrdude communications fail because the bootloader 
isn't running.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?
Using v1.0.1 under Win7 Pro; using a custom board.

Addendum- the offending line is line 88 in the AvrdudeUploader.java file.

Changing:
if((boardPreferences.get("uplo.path") != null && 
boardPreferences.get("bootloader.path").equals("caterina")))

to

if(protocol.equals("avr109"))

resolves the issue by checking the protocol used by the board rather than the 
bootloader name. This allows custom bootloader paths.

This is solved in Arduino 1.5 with the keyword:

upload.use_1200bps_touch=true
