My initial guess is that this is related to Bug 1068454. After the Cost Control App opens, the UI loads in the following order: Bottom half: No data used message -> "Mobile usage" and "Wi-Fi usage" text -> figure in the upper half -> No data used message is replaced with a list of per-app usage. I guess the b2gperf tools wait until the per-app usage list, but if no mobile data were used, the UI is considered loaded when the no data used message is present. But I dont' know why this happens a few days after the Gaia reversion 728132e3 landed. I looked into 689c4ad4 and 05f7d41f but found no clue.
Would this bug be a duplicate of bug 1072621?
