Problem uploading sketch in verify phase

Development Tools IDE 1.x
6

The bootloader is the STK500v2 at 115200 with a 16mhz clock.
I verified that avrdude will connect to the bootloader (avrdude -pm2561 -cstk500v2 -b115200 -P/dev/ttyUSB1)
avrdude -pm2561 -b57600 -cstk500v2 -P/dev/ttyUSB1 -U flash:w:Blink.cpp.hex
