When I saw it performed at the KC by the Cleveland Orchestra, the conductor just swept right on through not giving anyone a chance to applaud, cough or even move a muscle. I think it is accepted, but I think if it can be avoided, it will be. The cause of the 'rude' applause is that the quiet ending of the 3rd movement is mistaken as the symphony's ending. So the applause is still a faux pas and I guess if the conductor can prevent it, he/she will.
The third movement ends moderately loud and fast; the movement is marked
Allegro molto vivace (very fast and lively). It's the "triumphant" nature of the movement's ending that elicits applause, plus the overall tone sounds like a final movement. In a typical four-movement symphony, the third is typically a scherzo, which this particular movement is definitely not. What gives the symphony its "Pathetique" nickname is the fourth and final movement, marked
Adagio lamentoso (slow and profoundly sad). Most recordings have a typical few seconds pause between the movements. On a recording of the work by Sergiu Celibidache (live, of course), the conductor takes a Mahlerian pause between the movements, and it sounds just right.
